COM-HPC Carrier Layout
Thought for 15 sec
I’ll update Version 5.0 front-view visuals only so the Compute Module is drawn with correct 90 mm × 100 mm proportions and occupies the appropriate larger area. Version 4.0 stays locked.

Redone for Tiny Tim Version 5.0 front view.
Changes applied:
- Compute Module is shown much larger with intended 90 mm × 100 mm proportions.
- Carrier board remains 105 mm × 115 mm.
- Labels moved off the PCB as side callouts to reduce clutter.
- Version 4.0 remains locked and unchanged.

COM-HPC Mini Connector Search Results
Scope
Search started for the COM-HPC Mini type carrier-board connector needed for Tiny Tim Version 4.0 implementation.
No schematic, layout, image geometry, connector placement, or board dimensions were changed during this search.
Key Standard-Level Finding
Public COM-HPC Mini references indicate that COM-HPC Mini uses one 400-pin high-speed board-to-board connector. Larger COM-HPC Client/Server designs use two 400-pin connectors, but Mini uses a single connector.
Carrier-board side = male carrier plug / header.
Module side = female module receptacle.
Module side = female module receptacle.
The carrier plug determines the module-to-carrier stack height, typically 5 mm or 10 mm.
Candidate Connector Families
Samtec COM-HPC Carrier Plug Options
Samtec lists COM-HPC carrier plugs on its COM-HPC standard products page, with downloadable PDF prints and PADS footprint resources.
Table
| Stack height | Candidate P/N | Termination | Notes |
|---|---|---|---|
| 5 mm | ASP-230333-03 | Column | 400-position COM-HPC carrier plug; likely best 5 mm Samtec starting point. |
| 10 mm | ASP-230336-03 | Column | 400-position COM-HPC carrier plug for 10 mm stack. |
| 5 mm | ASP-214802-01 | Ball | 400-position COM-HPC carrier plug, 5 mm stack, ball termination. |
| 10 mm | ASP-209948-01 | Ball | 400-position COM-HPC carrier plug, 10 mm stack, ball termination. |
Other Samtec variants exist with different plating and ball/column termination options.
Amphenol COM-HPC Carrier Plug Options
Amphenol offers COM-HPC 0.635 mm pitch, 400-position open-pin-field array connectors.
Table
| Stack height | Candidate P/N | Notes |
|---|---|---|
| 5 mm | 10163479-14340T1LF | 400-position plug, 3.40 mm plug height, 5 mm mated stack. |
| 10 mm | 10163479-14840T1LF | 400-position plug, 8.40 mm plug height, 10 mm mated stack. |
| 5 mm with weld tab | 10171123-14340T1LF | 400-position plug with weld tab, 5 mm stack. |
| 10 mm with weld tab | 10171123-14840T1LF | 400-position plug with weld tab, 10 mm stack. |
Flux Library Status
Exact COM-HPC Mini / COM-HPC 400-pin carrier connector parts were not found in the Flux library during this pass.
Re-check after user request to import/create the connector: Samtec ASP-230336-03 is still not available as a usable Flux library part. Public web sources expose Samtec PDF print / footprint PDF / PADS resources, but no directly importable KiCad
.kicad_sym + .kicad_mod, Altium .SchLib + .PcbLib, Eagle .lbr, EasyEDA JSON, or ZIP library file was available to the current import tool.Library searches tried:
- COM-HPC Mini carrier board connector 400 pin board-to-board high-speed module connector.
- COM-HPC Mini keyword.
- COM-HPC keyword.
- Samtec ASP-230333-03 / ASP-230336-03 / ASP-214802-01 / ASP-209948-01.
- Amphenol 10163479-14340T1LF / 10163479-14840T1LF / 10171123-14340T1LF / 10171123-14840T1LF.
Closest Flux library results were unrelated high-density Hirose mezzanine connectors and should not be used for COM-HPC Mini.
Missing-part requests were submitted for:
- Samtec ASP-230333-03
- Amphenol 10163479-14340T1LF
Version 4.0 Selection
User selected:
Samtec ASP-230336-03 — COM-HPC 400-position male carrier plug, 10 mm stack height, column termination.
Reason: use the taller 10 mm stack height for more clearance and cooling.
Flux library status: exact part was not found during library search. A missing-part request was submitted for Samtec ASP-230336-03. Footprint import/create from Samtec PDF/PADS resources is likely required before real placement.
Prior Preliminary Recommendation
The earlier preliminary starting point was:
Samtec ASP-230333-03 — COM-HPC carrier plug, 400 position, 5 mm stack height, column termination.
Reason:
- It is a documented COM-HPC carrier plug.
- 5 mm stack height supports a lower-profile carrier/module assembly than 10 mm.
- Samtec provides PDF print and PADS resources, which should help create/import a footprint if the Flux library part is unavailable.
Fallback / alternate:
Amphenol 10163479-14340T1LF — COM-HPC 400-position plug, 5 mm stack height.
This has been superseded by the Version 4.0 user selection of Samtec ASP-230336-03 with 10 mm stack height for more clearance and cooling.
Critical Open Questions
- Do we need any alternate weld-tab / hold-down version for additional mechanical robustness, or is ASP-230336-03 acceptable as-is?
- Should a second-source Amphenol 10 mm equivalent be kept as fallback?
- Which exact COM-HPC Mini module will be used? The module vendor mechanical drawing may constrain connector stack height, keepout, and mounting-hole placement.
- Can the user provide the PICMG COM-HPC Mini Carrier Design Guide or module vendor carrier-board design files if available?
Next Actions
- Obtain/upload a usable EDA library package for Samtec ASP-230336-03: KiCad
.kicad_sym + .kicad_mod, Altium.SchLib + .PcbLib, Eagle.lbr, EasyEDA JSON, or a ZIP containing these files. PDF/PADS references alone are not enough for the current automated import path. - Define COM-HPC Mini module mechanical keepout and mounting holes.
- Confirm module-side connector compatibility and 10 mm stack clearance.
- Only after those are locked, place the real connector footprint on the 105 mm x 115 mm Version 4.0 board outline.
